Decode AVS in Virtualdub

[acrespo]

Question 13 in YV12 FAQ:

13. I installed AviSynth v2.5 and DivX5 (or one of the latest Xvid builds of Koepi), all I got is a black screen when opening my avs in Virtualdub/VirtualdubMod/CCE/TMPGEnc ?

Ok, apperently your video is not decompressed by DivX 5.02 (or Xvid). Go to your windows-dir and rename a file called MSYUV.DLL, or add the following to your registry file:

REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32]
"VIDC.YV12"="divx.dll"

Replace "divx.dll" by "xvid.dll" for xvid


Is there other codecs to decode YV12 AVS scripts in VirtualDub? And about YUY2?

For XviD 1.0 it should be xvidvfw.dll (I think, correct me if I'm wrong). You could also you use ffvfw for YV12. Huffyuv for YUY2.

Have you tried a program called vcswap. It allows you to turn vfw codecs on and off with ease. You don't need to install it either. It also gives you a list of direct show filters but as of version 1.5 that is it, no manipulation.



You can probably find the program here on the download page.

BTW, if I remember correctly TMPGEnc doesn't support YV12, you have to feed video to it in RGB24

You *DO* need a ConvertToRGB24() at the end of your script.

Does the AVS script open/preview OK in VirtualDUB ?

Anyway, why do you need to feed the AVS through VirtualDUB ? If you do it directly it will be much faster ...

Get http://www.avisynth.org/warpenterprises/files/readavs.zip
to make TMPEGenc recognize AVS file extension (you can open it anyway using the 'all files' template in the open file box).
